The theoretical calculations of the hadron internal structure is one of
the focuses of current high-energy physics. Basis Light-front
Quantization (BLFQ) is a recently developed non-perturbative method to
study the hadron structure via the Hamiltonian framework of the light-
front quantum field theory. The light-front wave function obtained
within this framework could be used to calculate almost all quantities
signifying the hadron internal structure, like PDFs, TMDs, GPDs and
DPDs. In this report, I will concentrate on our research of the
following three topics within the BLFQ framework:

1. I will show our results of all eight leading-twist TMDs of quarks
inside the proton and compare them with other theoretical predictions
and experimental extractions. I will also investigate the Sivers
asymmetry obtained using those TMDs and compare it with existing
experimental data.

2. I will show our preliminary results of the leading-twist T-even TMDs
of quarks inside the rho-meson (spin-1) and investigate their
properties.

3. I will show our preliminary results of the unpolarized double parton
distributions of quarks inside the rho-meson and investigate its
properties.
